EXHIBIT A Work Plan On May 26, 2017, the City of New Brighton was notified that the Metropolitan Council awarded a $150,000 Stormwater Grant to the Rice Creek Watershed District (RCWD) for the design and construction of a stormwater reuse system at New Brighton Lions Park. Craig Schlichting, New Brighton Director of Community Assets and Development, will serve as the project engineer, coordinator, and manager on behalf of the City, and will coordinate the project and funding through RCWD. The project will reduce the need for potable water for irrigation of the softball/lacrosse fields by connecting and expanding the existing irrigation system to a nearby stormwater pond. Task 1: Site Investigation Over the past two years, New Brighton has installed a lined storm water pond to treat runoff from a new housing development and Lions Park (scheduled to be completed in the fall of 2017). The City plans to remove contaminants with a package treatment plant including UV. The following section provides a brief summary of the total project cost and financing estimate; the anticipated water savings; and a preliminary investigation to determine the proper placement of the appropriate improvements. The existing normal water level of the pond is 4‐5 feet deep. The preliminary plan was to allow the normal water level of the pond to be seasonally adjusted to maximize the amount of surface water available for re‐use. In addition to the existing pond it is anticipated that a storage vessel will be included in the construction plans for irrigation. The preliminary investigation using the MIDS calculator estimated that 60 percent of the irrigation demand could be met. The City will refine the calculations based on the proposed equipment to determine the associated reduction percentage. The total estimated project costs and financing have been adjusted to include the initial capital costs of $200,000 (which includes $50,000 of City funds and the $150,000 Metropolitan Council Stormwater Grant). The City will collect a water sample at the pond (to be used for as an irrigation source). The samples will be sent to a fixed‐ based laboratory. The sample results will help determine the anticipated UV and filter criteria for the project. Water quality parameters evaluated will include turbidity, total suspended solids, E. coli, pH, chloride, zinc, and copper. These parameters were determined based on MPCA recommendations for public health, vegetation health, and irrigation system function. Task 2: Present to Parks Recreation and Environmental Commission Meeting Prior to advertising for bids, City staff will attend a Parks Recreation and Environmental Commission (PREC) meeting at the New Brighton City Hall. At the meeting, commission members will be provided with an overview of the project and will be allowed to ask questions or express concerns. Staff will provide the commission with educational materials including a schematic of the system, examples of similar systems, and a representation of the expected pond drawdown. PREC meetings are broadcast on local cable channels, but as an additional public education effort, a permanent information sign will be posted in the area to promote awareness of the project and stormwater management generally.
